DETAILED DESCRIPTION

As shown in FIG. 1, there is a trigger module 20 comprising a housing22, a safety 24, and a trigger assembly 26. The axis system 10 has alongitudinal axis 12, a vertical axis 14 and a lateral axes 16. Ingeneral, the axis system 10 is used to generally refer to orientationsof the components and not necessarily limiting to certain specificorientations. For example, the trigger module need not always bevertically orientated.

As shown in FIG. 3, the trigger assembly 26 comprises a trigger 28, anda disconnecter 30. In one form the disconnecter 30 shares a commoncenter at 32 where a pin passes therethrough. In general, thispass-through pin engages the housing of an AR 15. As further shown inFIG. 3, the longitudinally forward location 34 of the trigger 28provides a trigger sear surface 36 which is operatively configured toengage the hammer sear surface 46. The hammer 38 is pivotally attachedat the hammer pivot location 40. The hammer has a base region 42 and animpact region 44. Located at the base region is the hammer sear surface46 which, as mentioned above, is configured to engage the trigger searservice 36 to hold the hammer in a high-energy state position, otherwisereferred to as the cocked position. A spring member, such as a coilspring, is operably attached to the hammer 38 so as to bias the hammerin a longitudinally forward region.

As shown in FIG. 5, there is a cross-sectional view of the triggermodule 20 taken at line 5-5 of FIG. 2. As shown in FIG. 5, thedisconnecter 30 has the common center 32 where the disconnecter rotatestherearound. The disconnecter 30 is provided with a longitudinallyrearward region 50 and a longitudinally forward region 52. Located inthe longitudinally rearward region is a surface defining recess 54. Thesurface defining a recess 54 defines a spring holding location 56.

The trigger 28 is provided with a longitudinally rearward region 60 thatis provided with a surface defining a recess 62 which defines a triggerspring holding location. A sear spring is configured to fit within thetrigger spring holding location 62 and the spring holding location 56 torotate the sear 30 in a clockwise direction (which is referenced to FIG.5) with respect to the trigger 28.

In operation, the disconnecter sear 70 is configured to engage thehammer disconnecter 72 when the trigger 28 is pressed. In other words,when the trigger is pressed fully rearwardly the hammer will initiallyfall, and with a semi-automatic rifle, be cocked rearwardly. As thehammer is cocked rearwardly while the trigger is depressed, the hammerdisconnecter 72 will slide over the disconnecter sear 70 and thedisconnecter spring (not shown, but positioned between the recesses 62and 56) will compress and the hammer 38 will be retained in a rearwarddirection. As the trigger is allowed to travel longitudinally forwardly(the finger engagement portion 29 of the trigger), the disconnecter sear70 will disconnect from the hammer disconnecter 72, and as shown in FIG.3, the hammer sear surface 46 will engage the trigger sear 36 to retainthe hammer in a high-energy state until the trigger, more specificallythe finger engagement portion 29 of the trigger, is pressed again.

As shown in FIG. 2, the disconnecter adjuster 80 is shown where,referring ahead to FIG. 5, the disconnecter adjuster 80 is configured toadjust the rotational distance between the disconnecter 30 and thetrigger 28. The disconnecter adjuster receiving surface 82 of thetrigger can receive the pressure from the disconnecter adjuster whereina preferred forwardly disconnecter adjuster is a set screw and isaccessible from the vertical orientation when the hammer 38 is in aforward location.

Referring back to FIG. 2, there is an initial position adjuster 90which, in one form, can be a set screw that is attached to the trigger28. This initial position adjuster adjusts the initial position of thetrigger with respect to the housing 22, more specifically, the housingfloor 23.

Referring now to FIG. 6, which is taken from line 6-6 of FIG. 2, thisshows another cross-sectional view of the trigger module 20. As shown inFIG. 6, the safety adjuster 100 is shown. In some embodiments, thesafety 24 is a reversible adjustable selector and safety adjuster 100 isa set screw. For example, set screw 100 may be operatively configured toengage the longitudinally rearward region 60 of the trigger 28. In thisway, the set screw can be used to set the engagement of safety 24 toreduce the play between the safety and the trigger. This adjustmenthelps counter a safety selector hole positioned far enough on a lowerreceiver that it can allow a firearm to fire on a safety condition. Thesafety can be rotated by the safety lever 102 as shown in FIG. 6 as wellas in FIG. 4.
